  • processor 206 sets an empty mailbox flag in memory 208 and actuates display 210 for indicating an empty mailbox (i e , no mail)
  • Figure 3C shows an exemplary icon displayed by display 210 for indicating an empty mailbox If this icon is not displayed by display 210, then the subscriber will know that mailbox 1 12 contains at least one unread mail message. Again, if the optimized mode of operation is selected by the subscriber, network traffic is minimized because the empty mailbox notification is sent only once.
  • VMS 104 can send a predetermined percentage- full notification to PCD 118 indicating that the amount of messages stored in mailbox 112 exceeds a predetermined percentage-full threshold.

  • Other predetermined percentage-full thresholds can be used in addition or in the alternative to the exemplary 50% full threshold shown in Figure 4 with corresponding icons indicating the additional or alternative thresholds.
  • VMS 104 can send a message priority notification to PCD 118 that depends upon the particular level of priority of the message.

Abstract

L'invention concerne un système de communication (100) comprenant au moins un dispositif de communication mobile doté d'un indicateur de messages, et un centre de messagerie vocale (194). Le centre de messagerie vocale comprend une boîte vocale (112) associée à au moins un dispositif de communication mobile (118). Le centre de messagerie vocale adresse un appel à la boîte vocale associée à un dispositif de communication mobile au moins, pour l'enregistrement d'un message lorsque le dispositif de communication mobile n'est pas en état de recevoir l'appel. Le centre de messagerie vocale optimise la communication entre celui-ci et le dispositif de communication mobile en envoyant un premier indicateur de message au dispositif de communication mobile lorsqu'un message vocal est enregistré et que la boîte vocale ne contenait auparavant pas de messages, un deuxième indicateur de message lorsque la boîte vocale est pleine, et un troisième indicateur de message lorsque la boîte vocale est vide.
